The – DAC6578 (10 bit): 0.5LSB INL devices are monolithic, provide good linearity,and – DAC7578 (12 bit): 1LSB INL minimize undesired code-to-code transient voltages • Glitch Energy: 0.15nV-s (glitch). • Power-On Reset to Zero Scale or Midscale The devices use a versatile, 2-wire serial interface that is I2C-compatible and operates at clock rates of – Devices in the TSSOP Package Reset to up to 3.4MHz. Multiple devices can share the same Zero Scale bus. – Devices in the QFN Package Reset to Zero The devices incorporate a power-on-reset (POR) Scale or Midscale circuit that ensures the DAC output powers up to • Ultra-Low Power Operation: 0.13mA/ch at 5V zero-scale or midscale until a valid code is written to • Wide Power-Supply Range: +2.7V to +5.5V the device. These devices also contain a power-down • 2-Wire Serial Interface ( I2C™ compatible) feature, accessed through the serial interface, that reduces the current consumption of the devices to • Temperature Range: –40°C to +125°C typically 0.42mA at 5V. Power consumption is typically 2.32mW at 3V, reducing to 0.68mW in power-down APPLICATIONS mode. The low power consumption and small • Portable Instrumentation footprint make these devices ideal for portable, • Closed-Loop Servo Control battery-operated equipment. • Process Control The DAC5578, DAC6578, and DAC7578 are drop-in • Data Acquisition Systems and functionally-compatible with the DAC7678. All devices are available in a 4x4, QFN-24 package and a TSSOP-16 package.
